The objective of this school is to provide an overview of the recent progresses in the mechanics and physics of fracture in solids. The six courses will provide a comprehensive understanding of the macroscopic failure behaviour of solids from the description of the microscopic failure processes and their coupling with the microstructure.

Fracture of materials is a multi-scale process that couples the continuum scale from which elastic energy is released to the microstructure scale where this energy is dissipated through damage mechanisms at the crack tip vicinity. For that reason, the microstructural features of materials greatly influences their failure behaviour. Powerful approaches have been recently developed to bridge length scales in fracture phenomena and this school will provide a pedagogical overview of the concepts and tools that allow to go from the small to the large scale and, vice & versa, the basic rules for the design of tough solids.

Three fundamental questions will be addressed during the school: (i) The relation between the microstructural features of materials and their effective fracture properties, (ii) the role of damage mechanisms and non-linear deformations near the crack tip on the failure behavior of solids and (iii) the role of dynamic inertial effects during fast fracture.
